Subject: Inline sha_local.h in sha1dgst.c.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=f70cf6c6f2679184e3c46370ba3e1eb5adfb4f0e;p=openbsd

Inline sha_local.h in sha1dgst.c.

Nothing other than sha1dst.c uses this header - pull it in to sha1dgst.c
directly (sha_local.h will be removed at a later date).
